Transmission properties of tapered optical fibres: Simulations and experimental measurements
Optical fiber technology (Print)
A B S T R A C T We measured the transmission of tapered and untapered optical fibres as a function of input beam numerical aperture at 635 nm. The tapered fibres were fabricated with an adiabatic tapering process from graded and stepindex fibres with 50 μm core diameters to form a 100 mm long taper with 5:1 taper ratio. We tested tapered graded-index and step-index fibres fabricated from commercial Thorlabs products and a custom graded-index taper. The 5:1 tapered graded-index fibre can give adoi:10.1016/j.yofte.2021.102632 fatcat:3dfyguf4uzakpgux4qonnabyii
